the volatile constituents of the aerial parts of vervain (verbena officinalis l.) cultivated locally were investigated. analysis of the volatile fraction by gc and gc-ms is described. compounds were identified by various methods, the major compounds being 3-hexen-1-ol (7.28%), 1-octen-3-ol (32.76%), linalool (4.66%), verbenone (20.49%) and geranial (7.22%).

We prove that for a prime number p greater than 6000, the Olson's constant for the group Zp ⊕ Zp is given by Ol(Zp ⊕ Zp) = p − 1 + Ol(Zp).

The structure of the title compound [alternatively called (R)-(-)-1-aza-bicyclo-[2.2.2]octan-3-ol], C7H13NO, at 100 K has hexa-gonal (P61) symmetry. The structure shows a twist along the C-N pseudo-threefold axis. In the crystal, mol-ecules are linked via O-H⋯N hydrogen bonds, forming infinite chains along the c-axis direction. The crystal studied was twinned by merohedry (twin law: 010, 100, 0...

In recent years, the demand for olive oils from Douro region (Portugal) has increased in line with wine. Thus, it is essential to characterise these evaluate them. Therefore, this work describes sensory and volatile profiles of produced region. These were mainly identified as ripe fruity. Among olfactory gustatory sensations, attributes dried fruits, tomato, apple, tomato leaves, banana, lavend...

BACKGROUND The autonomic nervous system plays a central role in the maintenance of hemodynamic stability. Cardiac autonomic dysfunction may result in serious complications, such as sudden cardiac death. Heart rate variability (HRV) is significantly reduced in patients undergoing chronic hemodialysis (HD). The aim of this study was to evaluate the effect of on-line hemodiafiltration (OL-HDF) on ...

BACKGROUND Delayed onset of lactogenesis (OL) is most common in primiparas and increases the risk of excess neonatal weight loss, formula supplementation, and early weaning. OBJECTIVE We examined variables associated with delayed OL among first-time mothers who delivered at term and initiated breastfeeding (n = 431). DESIGN We conducted in-person interviews during pregnancy and at days 0, 3...

Inhibition of nitric oxide synthase (NOS) activity in vivo impedes hypertrophy in the overloaded rat plantaris. We investigated the mechanism for this effect by examining early events leading to muscle growth following 5 or 12d of functional overload. Male Sprague-Dawley rats (~350g) were randomly divided into three treatment groups: Control, L-NAME (N-nitro-L-arginine methyl ester; 90mg/kg/d),...

The NASA Catchment land surface model (CLSM) is the land model component used for the Modern-Era Retrospective Analysis for Research and Applications (MERRA). Here, the CLSM versions of MERRA and MERRA-Land are evaluated using snow cover fraction (SCF) observations from the Moderate Resolution Imaging Spectroradiometer (MODIS). Moreover, a computationally-efficient empirical scheme is designed ...

BACKGROUND The aim of this pilot study was to test the feasibility of a bihormonal (glucagon and insulin) closed-loop (CL) system by challenging the system with two meals and 30 min exercise. METHODS Ten patients with type 1 diabetes treated with continuous subcutaneous insulin infusion underwent a standardized protocol on three different occasions: 40 g carbohydrate breakfast followed 2 h la...
